LADLE FOR POURING STEEL.

SPECIFICATION forming part Of Letters Patent NO. 540,292, dated June 4, 1895.

Application filed July 26, 1894- Serlal lilo. 518,672. (No model.)

To aZZ whom it may concern:

Be it known that I, NIOHLAS J. ALTMEYER,

.a citizen of the United States of America, re-

siding at New Castle, in the county of Law rence and State of Pennsylvania, have invented certain new and useful Improvements in Ladles for Pouring Steel, of which the following is a specification.

My invention relates to ladies used in connection with converters, in the manufacture of steel.

My said invention is illustrated in the accompanying drawings, in which Figure l is a side view of theladle with its shield and carrier. Fig. 2 is a detail view showing the nozzle. Fig. 3 is a view of the ladle a quarter-turn from Fig. 1. Fig. 4 is a plan view of a part of the ladle, and Fig. 5 is a detail view of the shield and carriage a quarterturn from that shown in Fig. 1.

In the drawings A represents a ladle which, except in the particulars hereinafter explained is the same as those heretofore used; but instead of a hole in the bottom, for the discharge of the metal, I have provided a nozzle, a, which is located on the front of the ladle, near the top. In the nozzle is a brick or other fire proof lining piece I), and behind this a chamber or recess a, behind which is'a gate cl forming the inner wall of the recess a. The gate d is moved by raising or lowering it, in guides, and the movement is imparted or controlled by means of any suitable levers as e and f.

The ladle is supported on trunnions h with any suitable means for turning, part of which means are indicated at i.

Then the metal is poured by the tipping of the ladle, the gate is raised sufficiently to allow the metal to pass under it to the nozzle, but not above the scum which is thereby held back during the pouring.

The nozzle recess is made'of a removable casting, and the nozzle is also made of brick and in a single piece removable from the recess. In the form shown I have provided a plate or casting L, adapted to fit upon the edge of the ladle, and to form a guard over the nozzle to prevent slopping over of the This casting or cover supports the metal.

fulcrum of the lever and forms also part of the guide for the gate. The cover is held to the ladle by clamps m m.

In connection with the tipping ladle, I have provided a movable shield O which is supported upon a carriage P. In order that the shield may be adjusted accuratelyunder the nozzle and over the mouth of the mold, at the proper height, I have mounted it upon an arm 10 which has at its outer end a frame in which the shield sits. The innerend of the arm is fixed in a block q, having a sliding stem which fits in a vertical hole in the top of the post 0'. It is raised or lowered by a lever s, and held by a notched segment 25. The post turns in a socket to adapted to slide on a dovetailed guide a on the carriage, it being moved to and fro by the lever o. Thus the shield may be arranged without accurately moving the carriage and put in position to allow the metal to flow through it and be guided thereby to the mold. By this form of ladle, the work is facilitated, the life of the ladle is prolonged and the troublesome formations on the bottom of the ladle are prevented.

I claim- 1. In combination with a tipping-ladle, having a nozzle at its upper edge, and a suitable recess in rear of the nozzle, a gate and means for moving and controlling said gate, the said gate being arranged to slide vertically behind said recess, whereby the scum maybe held back in the pouring by the lower end of the gate, substantially as described.

' 2. In combination with the carriage, a movable shield mounted upon an arm p, arranged to hold the shield, said arm being fixed in a block on a sliding stem fitting in the top ofa post, and means for moving said block, vertically, the said post being arranged to turn in a sliding socket on the carriage and provided with 'a lever for moving it, all substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
